T all whom it may concern:

Be it known that I, CHARLES A. JUENGST,

a citizen of the United States, residing at Croton Falls, in the county of Westchester and State of New York; have invented an those where the signatures are held by staples.

My invention relates to a group of stapled signatures ready to be ut into a cover to form a book, and the ob ect of my invention is the production of a book of collated stapled signatures capable when open of lying In carrying out my invention the signatures composing the book and connected together are connected together by staples bridging over the backs of the signatures, with one end of a staple entering through the back of one signature and the other end of the sta le entering through the-back of the next a jacent signature and the respective free ends within-the signatures bent toward the body of the sta le.

The various stap es holding together the respective signatures for each book are set in a staggered relation to one another, so as to avoid the increase of thickness that would arise if the staples were all set in line, but I do not limit myself to any particular arrangement of staples for thus connecting the signatures.

In the-drawing, Figure 1 is a perspective view looking at the back of a number-pf connected signatures, showing the device of my improvement. Fig. 2 is a broken or detached plan showing a portion of adjacent signature backs in large size and with a staple in position' Fig. 3 is a cross section at the dotted line an, ac, of Fig. 2. ig. 4 is a plan showing part of a signature thus stapled as opened out. Fig. 5 is an end elevation of the signatures as shown in Fig. 4:,showing thefiat opened out position assumed by a number of connected signatures and Fig. 6 is a broken plan showing a form of my invention.

Referring particularly to Fig. I, a a a a a a a a represent the respective signatures as connected together by staples. b represents the respective staples and b b the free ends of each staple. As will appear especially from Figs. 1 and 2, the respective staples are placed diagonally, bridging or extending across between the central portions' of the backs of"adjacent signatures with their free ends entering the backs of the adjacent signatures; the free ends I)? and b of the staple being bent toward the body member and toward the o posite end of the next staple'which according to Fig. 4, ap-

ears at the center of a signature when itis aid open- I aim also to prevent the accumulated thickness of the book of signatures by staples placed in this manner, and to that end prefer to stagger the various staples with relation to one another as will particularly I appear by reference to Fig. 1. In this manner the inturned free ends of one staple do not come into opposition with the inturned ends of the next adjacent staple, consequently there is ample room for the inturned ends Without coming into transverse contact or close relation with one another; this would'in'crease the thickness of the book and also the compression against the paper..

which would tend to cut the same. Where two inturned ends of the staples in line are separated by the thickness of two signatures and come into every third signature there is always room to accommodate these ends and this condition will be apparent from Fig. 1 of the drawing.

As shownin Fig. 1, the centrally placed series of sta les run in the opposite direction to those of the end series. The essential object in thus running the staples of the series in opposite directions, viz: to prevent the staples of the series acting as hinges and permitting the swinging and conse uently opening out of the signatures as wou d be the case ,ment of the staples across the backs of the collated signatures.

I claim as my invention:

, 1. A series of si natures and a series of staplesconnecting t e same for binding, each staple bridging directly over the folds from A one signature to another, with 1' the free ends of a staple entering the signatures. and turned over. 7 j

2. A series of signatures and a series of staples connecting the same for binding, each staple bridging diagonally over the back from one signature to thenext, with the free ends of the staple entering the adjacent signatures and turned over.

3. A series of signatures and a series of staples connecting the same for binding, each staple bridging diagonally over the back from one signature to the next adjacent signature, with the free ends of the staples passing centrally into the folds of the adjacent signatures and turned over to lie closely staples in series connecting the same for binding, each staple bridging diagonally over the back from one signature to the next adjacent signature, with the free ends of the staples passing centrally into the folds of the adjacent signatures and turned over to lie closely within the folds of the signatures, with the staples of each series running in like direction and the staples of one series running in a direction which makes with the lines of the back folds of the signatures an angle equal and opposite to that of the staples of the other series.

6. A series of signatures and three groups of staples connecting the same for binding, one of the groups being central in the length of the folded backs of the signatures and the other two groups being adjacent to the ends of the folded backs, the staples of the end groups inclined alike and running in the same direction diagonally and the staples of the central group running in a direction which makes with the line of the back folds of the signatures an angle equal and opposite to thatof the staples of the other series, and every staple bridging diagonally over the back from one signature to the next adjacent signature, the free ends of the staples passing centrally into the folds of the adjacent signatures andturncd over to lie closely Within the folds of the signatures.

Signed by me this 2d day of December, 1907.
